Which one should you ship with? Here is the side-by-side panel verdict, pricing read, reviewer split, and community vote comparison.

Agent Armor is a lightweight governance layer for AI agents, written in Rust and designed to intercept every agent action before execution. It sits in front of LangChain, CrewAI, AutoGen, or Claude Code and runs each proposed action through an 8-stage decision pipeline: intent classification, credential leak scanning, rate limiting, resource scoping, behavioral fingerprinting, semantic deduplication, human-review escalation, and final allow/block. The project is MCP-aware and can intercept tool calls at the protocol level, which means it works regardless of which agent framework you're using. Actions that pass all 8 layers execute normally; those that fail can be automatically blocked, held for human review, or rewritten to a safer equivalent. A live dashboard shows agent activity, pending reviews, and anomaly alerts. Version 0.3.0 arrived as a Show HN today and hit the front page. The author, Edoardo Bambini, built it after a production incident where a coding agent attempted to overwrite git history on the main branch. The timing is good — as more teams ship agents to production, "what guardrails do I put between the agent and the real world?" is an increasingly urgent question.

AgentAuditKit is an open-source security scanner purpose-built for the emerging class of MCP-connected AI agent pipelines. Where traditional static analysis tools know nothing about tool descriptions, prompt injection surfaces, or trust boundary semantics, AgentAuditKit speaks the language of agentic systems. It ships with 77 detection rules across 13 specialized scanners that cover the full OWASP Agentic Top 10 and MCP Top 10 threat lists — all 20 out of 20. The scanner catches hardcoded secrets, shell injection in tool handlers, prompt injection embedded in MCP tool descriptions, rug pull patterns (tools that change behavior after trust is established), tainted data flows between agent layers, and trust boundary violations between orchestrators and sub-agents. It runs entirely offline, integrates as a GitHub Action, and maps every finding to EU AI Act, SOC 2, and HIPAA compliance frameworks. Install with pip and point it at your project. Internal benchmark data cited in the repo found vulnerabilities in 43% of public MCP servers tested. The timing is pointed: as MCP adoption accelerates from hobbyist to enterprise, the attack surface is growing faster than the security tooling. AgentAuditKit is the first dedicated scanner addressing this gap, and it's free.
Reviewer scorecard
“I've been looking for exactly this: a framework-agnostic safety layer I can drop in front of my agents without rewriting them. The credential leak scanning alone is worth the integration cost — agents have a bad habit of echoing secrets into tool calls.”
“Every team shipping MCP servers needs this in their CI pipeline yesterday. The GitHub Action integration is clean, the OWASP mapping gives you a compliance paper trail, and it catches attack surfaces that no general-purpose linter would ever find. Runs offline so no source leaks.”
“An 8-stage pipeline on every agent action is a lot of latency overhead, especially for interactive agents. And sophisticated attackers will study the classifier patterns — once Agent Armor is widely deployed, the 8 stages become an adversarial target. This is good for basic hygiene, not a security guarantee.”
“77 rules is a small ruleset for a security tool covering 20 OWASP categories — that's under 4 rules per category on average. The 43% vulnerability rate claim needs an independent audit; it could reflect a biased sample of low-quality public repos. I'd treat this as an early-warning complement to proper security review, not a replacement.”
“The agent governance market will be worth more than the agent framework market within 3 years. As AI agents take real-world actions with real consequences, something has to sit between the model and the world. Agent Armor is an early but serious attempt at the right architecture.”
“Security tooling always lags deployment by 2-3 years. The fact that a dedicated MCP security scanner exists this early in the MCP adoption curve is genuinely encouraging. This is the beginning of an agentic security ecosystem — expect a full stack of SAST, DAST, and runtime monitoring tools to emerge around it.”
“The dashboard is beautifully designed for a security tool — clear threat visualization, pending review queue, agent behavior timeline. I actually want to run this just to see what my agents are attempting even when nothing looks wrong.”
“As someone building AI-powered creative tools that use MCP for file system access, knowing there's a scanner that specifically checks for prompt injection in tool descriptions is a relief. Creative tools handle sensitive IP — this kind of audit tooling gives studios the confidence to actually ship agentic features.”
